To Install the Interface Tip Seal
Materials needed
• Interface tip seal (G3870-20542)
The interface tip seal must be in place for the CI source, the EI XTR source,
and HES.
Procedure
1 Verify that the CI source, EI XTR source, or HES is installed. This tip seal
and its spring must not be installed when an EI SS or Inert source is
installed.
2 Place the tip seal spring over the end of the interface.
3 Remove the interface tip seal from the ion source storage box, and place it
over the end of the interface.
Electrostatic discharges to analyzer components are conducted to the side board
where they can damage sensitive components. Wear a grounded antistatic wrist strap
and take other antistatic precautions before you open the analyzer chamber.
